Oestrogen hormone deficiency in menopause leads to symptoms of which hot flushes, night sweats, insomnia and mood changes are the most frequent and, ultimately, worsen the quality of life. The gradual decline of oestrogen from peri-menopause results in altered function of many neurotransmitters, such as dopamine, melatonin and neuropeptides including beta-endorphins, which modulate the function of the hypothalamus and are involved in body thermoregulation.
